  1. 6. Water quality monitoring with Sentinel 2 in small watercourses : Investigating the measurability of phosphorus using proxy data

    Master-uppsats, Stockholms universitet/Institutionen för naturgeografi

    Författare :Caroline Morin; [2023]
    Nyckelord :Optical remote sensing; Sentinel 2; Phosphorus; Total suspended matter; Turbidity;

    Sammanfattning : Inland water has for a long time showed vast stress due to eutrophication, mainly caused by increased levels of phosphorus. Applying remote sensing as a tool for monitoring water parameters has long been used. LÄS MER

  3. 7. The chemical evolution of the Milky Way: pushing APOGEE to higher precision and accuracy

    Master-uppsats, Lunds universitet/Astrofysik; Lunds universitet/Fysiska institutionen

    Författare :Erik Fridén; [2023]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : In the recent decade, a rapid increase in all-sky spectroscopic surveys has occurred, and with it, the wealth of observational data and information on our Galaxy. Consequently, numerous detections of new structures, such as new open clusters, accreted and in-situ components, are discovered. LÄS MER

  4. 8. Spatial downscaling of gridded soil moisture products using optical and thermal satellite data: the effects of using different vegetation indices

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Tómas Halldórsson Alexander; [2023]
    Nyckelord :Physical Geography and Ecosystem Analysis; Remote Sensing; Soil moisture; Downscaling; Vegetation index; Earth and Environmental Sciences;

    Sammanfattning : Soil moisture (SM) plays an important role in the exchange of heat and water between the surface and atmosphere, impacting water and energy cycles and the climate. Satellite remote sensing offers a global-scale estimation of SM; however, the coarse resolutions of satellite SM products, typically ranging from 25-50 km, are unsuitable for regional analysis.

  5. 9. Learning in physics with simulation : Students’ needs & perceptions of the interaction with Algodoo, and learning in physics

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Seyma Ikra Koyuncu; [2023]
    Nyckelord :computational thinking; stem; simulations; physics; modelling; digital tools; digital content; computational thinking; stem; simulering; fysik; modellering; digitalt verktyg; digitalt innehåll;

    Sammanfattning : Initiatives to implement computational thinking and science, technology, engineering & modelling into learning processes have been taken by many authorities worldwide, and in Sweden as well. The Swedish government made changes in the high school curriculum in order to develop student’s digital competence including programming which has been in force since June 2018 (Skolverket, 2018).

  7. 10. Näringsämnen och metaller i sediment och blåmusslor från Hanöbukten - En analys av marin miljöpåverkan från massabruk

    Master-uppsats, Lunds universitet/Centrum för miljö- och klimatvetenskap (CEC)

    Författare :Elvira Källberg; [2023]
    Nyckelord :Föroreningar; massabruk; blåmusslor; sediment; Earth and Environmental Sciences;

    Sammanfattning : The pulp industry is important for creating sustainable paper products and for the Swedish economy. However, the industry has historically polluted marine environments through its emissions. This study aims to analyse the effects of the pulp mill Södra Cell Mörrum on the marine recipient Hanö Bay in the southern Baltic Sea. LÄS MER
